I agree with A & C. The thrust of the SID is detecting corrosion. Good regular maintenance will look out for and catch developing corrosion and stop it from getting a hold. Cheap maintenance will basically eschew any indepth structural inspections allowing corrosion to fester.

The SID will be a killer for these aircraft because when the dark corners are opened repairs are going to be required. Since all of the SID inspections are for major structural members, repairs are going to be uneconomic for a lot of marginally maintained aircraft.

The other issue is there is both calendar and hour limits. At 20 years of airframe age, which is every legacy Cessna single, all the big inspections kick in regardless of airframe hours. This is going to be a big all once hit even for good aircraft.

Finally this is not a one time deal. There are continuing inspections required and for aircraft over 12,000 hours the inspection interval is dramatically shortened.

So far in Canada the SIDs are not mandatory for private aircraft and most flying schools have written their Maintenence Control Manuals (whuch are approved by Transport Canada) so they are not obligated to perform the SID,s. However there are indications that TC may mandate them anyway.

If these are inspections are made mandatory for private aircraft my SWAG is that half the fleet of the privately owned single engine Cessna,s will never fly again....
